If you use the flash at a camera-to-subject distance of one meter or closer, vignetting may
occur. Back off to more than 1 meter from the subject to take flash photographs.
A hood attached to the lens while taking photographs using the built-in flash can obstruct
the light from the flash and cause vignetting. When using the built-in flash, always
remove the hood from the lens.
The following lenses can cause vignetting with the built-in flash. When using the following
lenses for flash photography, we recommend using a dedicated external flash unit.
• Large-diameter lenses such as the EF20-35mm f2.8L and the EF28-70mm f2.8L.
• Super-telephoto lenses such as the EFSOOmm f2.8L and the EF600mm f4L.
The built-in flash and an external flash cannot be used together.
The built-in flash cannot be used when an external flash or the accessory shoe cover is
attached to the accessory shoe.
Before attaching an external flash, retract the built-in flash.
